Deerfield Reservoir is located 20 miles west of Hill City, SD. The Bureau of Reclamation manages the dam and water. Castle Creek flows into and out of the reservoir and provides additional fishing opportunities. Ice fishing, snowmobiling and ice skating are popular winter sports here. The complex has three campgrounds, two picnic areas and the Deerfield Lake Loop Trail (Trail #40L).
There are two boat launch areas; one at Dutchmen Campground (south side) and one at Custer Trails. Please note: The Custer Trails boat dock is not placed as the dock sustained extensive damage from wind and other elements. Gravel has been laid at this location and boats can still be launched there, however, sandals and/or footwear that can get wet is recommended.
Travel on the reservoir is limited to five miles per hour and there is a no-wake restriction which provides for peaceful fishing and boating experiences.
Reservoir water levels and boat ramp data can be found on the Bureau of Reclamation website for Pactola and Deerfield Reservoirs: http://www.usbr.gov/gp/boat/
